Sunan Abi Dawud, Hadith 1224 ⓘ
Narrated Aisha, Ummul Mu'minin: Ata' ibn AbuRabah asked Aisha: Can women offer prayer on a riding beast? She replied: They were not permitted to do so in hardship or comfort. Muhammad ibn Shu'ayb said: This (prohibition) applies to the obligatory prayers.
حَدَّثَنَا مَحْمُودُ بْنُ خَالِدٍ، حَدَّثَنَا مُحَمَّدُ بْنُ شُعَيْبٍ، عَنِ النُّعْمَانِ بْنِ الْمُنْذِرِ، عَنْ عَطَاءِ بْنِ أَبِي رَبَاحٍ، أَنَّهُ سَأَلَ عَائِشَةَ - رضى الله عنها - هَلْ رُخِّصَ لِلنِّسَاءِ أَنْ يُصَلِّينَ عَلَى الدَّوَابِّ قَالَتْ لَمْ يُرَخَّصْ لَهُنَّ فِي ذَلِكَ فِي شِدَّةٍ وَلاَ رَخَاءٍ . قَالَ مُحَمَّدٌ هَذَا فِي الْمَكْتُوبَةِ .
